Carbo - hydrate. Glucose is a common carbohydrate that will show up again and again as we discuss cell chemistry: its formula is C6H12O6. Table sugar, sucrose, is two single sugars bound together: a disaccharide simple sugar. Sugars can be anything from a single sugar molecule up to several bound together.
The two sides of the DNA molecule are Deoxyribose and phosphate these two molecules are what make up the two sides of DNA.
Then after the DNA molecule is in two separate pieces, another molecule called DNA polymerase makes a new strand that matches each of the strands of the split DNA molecule. Each copy of a DNA molecule is made of half of the original (starting) molecule and half of new bases.
